# Build binary and make sure there is at least an empty key file.
# This is useful for GCP App Engine custom runtime builds, because
# you cannot use multiline variables in their app.yaml, so you have to
# build the key into the container and then tell it where it is
# by setting OAUTH2_PROXY_JWT_KEY_FILE=/etc/ssl/private/jwt_signing_key.pem
# in app.yaml instead.

Potentially breaking change: docker user & group Run as non-root user and group In the unlikely event that you are currently persisting data to disk then this change may break file read/write access due to a change in the UID/GID that the oauth2_proxy process runs as. Run as non-root system user and group `oauth2proxy` with UID/GID `2000` to avoid clashing with typical local users. An alternative to creating a separate user is to ~~chown binary and~~ run as `USER nobody`, which also works, can amend this PR if required. Least access privileges.
